摘要
本文根据流域蓄泄关系和霍顿地貌律,讨论了基于串并联线性水库原理的流域汇流模型,导出了一,二和三级流域的瞬时单位线,并初步论证了这种理论模型的精度。作为这种模型的应用,本文还提出了计算降雨分布不均匀清况下的洪水过程线的计算方法和步骤,还附了一则计算实例。
A watershed routing model,employing the storage-outflow theory of watershed and the Horton geomorphologic law and designed on the principles of linear reservoirs connected in series and in parallel,is discussed in this paper.The instantaneous unit hydrographs of one-order,two-order,and three- order watershed are derived.This kind of theoretical model is expounded and proved.As an application of this model to the runoff estimation,an approach is proposed of constructing responsed hydrograph to rainfall excess which is characterized by uneven distribution both in time and in space.A case study is also attached to this paper.
